I have the Acer Aspire 2920 and when I turn it on the Acer startup screen appears then the screen goes blank but the computer is still powered on.

Ideally I would like to overcome this without restoring to factory settings but will do if need be.

Having seen other advice I have tried holding down alt and pressing f10 at startup (which has worked on another Acer) and have also tried pressing f8 at startup but neither of these have worked and now when turning on the laptop I get the acer screen foillowed by the message:
Disk error
Press any key to restart

but no key will restart the laptop.


Please help
